T A T E SAMUEL HYSLOP, 0F NEWTON, MASSACHUSETT.

Be it known that I, SAMUEL HYsLoP, a citizen of the United States, and resident of -Newton, county of Middlesex, and Commonwealth of Massachusetts, have invented an Improvement in Thread C'learers, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to thread or yarn clearers for use on winding machines and the like for the purpose of arresting the feeding of the thread when a knot, snarl, bunch, slub or other imperfection approaches the device.

In the present embodiment of my invention illustrated and described herein,

Fig. 1 is a plan;

Fig. 2, a front view, partly broken out;

Fig. 3, an end view from the right, Fig. 1, showing the device in a horizontal position for clearness, and partly broken away;

Fig. 4, a plan, with the guide broken away, and the thread carrying arms in operative or thread breaking position; and

Fig. 5, a partial plan of the two arm ends in horizontal position for clearness with the thread therein.

Referring first to Figs. 1, 2, 3, my novel device is shown as comprising an angularly shaped base member 1, provided with a split arm 2, adapted to be secured, as by a screw 3, to any suitable support as a rod, not shown, on the winding or other machine, not shown.

The base 1, Figs. 1, 3, 4, is provided with a plurality, herein two, of pins or posts 4 on which are pivotally mounted arms 5 with hubs 6, the outer ends of the arms being provided with upwardly extended posts 7 These posts are slotted vertically at 8 to form thread carrying grooves. On the posts 7 are the hubs 9 of a link 10 movably connecting the two arms 5.

The hubs 9 are also slotted vertically at 11, Figs. 1, 4, to register with the slots 8 in the posts 7 so that normally the thread will be fed through the hubs 9 and posts 7 in a substantially straight line. The rear halves of the tops of the posts 7 and hubs 9, Fig. 3, are cut away and incline upwardly and rearwardly, Fig. 3, to cooperate with the edge 12 of the guide 13 also secured to the rear of the base 1 by nuts 13 and by means of which the thread, when dropped by the CLEARER.

operator, will naturally slide into the slots 8 and 11. v

The base 1 also carries two laterally ex]- tended posts or thread supports 14 which are positioned slightly higher than the grooves 8, 11, to carry the thread and to prevent it from chafing against the bottom of the slots 8, 11.

In use, the clearer is positioned on the winding or other machine, preferably atan angle, Fig. 2, so that the arms 5 will naturally swing by gravity to the left, to the position shown in Fig. 1, one post 14 acting as a stop for the arms, with the grooves 8, 11, in the same plane.

The thread 15, Fig. 2, may be fed from a cop, 16 througl'i the device and to a bobbin or cop at the right of the device, not shown.

The thread will pass readily through the slots 8, 11 until a knot, slub or other en'- lar'gement of the yarn strikes the left hand, Fig. 1, hub 9, when the tension on the thread will cause both posts 7 and arms 5. to be im-' mediately swung to the right, Fig. '4, and the yarn or thread will be offset, Figs. 4, 5, by the turning of the posts 7 relative to the hubs 9 and consequently the thread will be crowded between the outer wall of the post 7 and the inner wall of the hub 9 through the distance that these faces overlap, owing to the non-alignment of the slots 8 and 11;

and the friction thus created between the walls and offset yarn sections will cause the yarn or thread to break under the tension imposed on it usually at the right of the right hand hub 9, Figs. 1, 4.

The knot can then be removed and the broken thread tied and the operation of the machine resumed. While one post 7 will frequently provide all the friction that is necessary to break the thread, I prefer to employ two or more arms and posts, as less friction on each arm is required, and it permits greater degree of variance in the size of thread that may be used in a given case, with equal certainty of operation.

My invention is not limited to the precise embodiment illustrated and I claim:

1. A thread clearer comprising a base, a plurality of slotted arms pivoted thereon, a slotted link connecting said arms, its slots registering with the slots in the arms to receive the thread and constructed and arranged to form with said arms offset sections in the thread whenthe arms are swung.

2. A- thread clearer comprising a base, a

plurality of thread carrying slotted arms pivoted thereon, a link connecting the arms and having a slot registering with the arm slots and constructed and arranged to swing the link slot out of registering position when the arms are turned.

3. A thread clearer comprising a base, a plurality of slotted arms thereon, an arm connecting member slotted to register with the arm slots and receive the thread and constructed and arranged to swing its slot out of the plane of the arm slots when the latter are moved.

4. A thread clearer comprising a base, a plurality of slotted arms movable thereon, an arm connecting link slotted in the same plane as and on the arms and constructed and arranged to swing with, and throw the slot out of the plane of the arm slot-s.

5. A thread clearer comprising a base, a plurality of registering slotted thread carrying members movable thereon and constructed and arranged to move and throw the slots out of relative registering position under the influence t slubs on. the thread.

6. A thread clearer comprising a base, a plurality of slotted thread carrying members movable thereon normally forming a continuous slot therethrough for the thread and constructed and arranged to break the continuity of the slot when swung from normal positions.

7. A thread clearer comprising a base, an arm with a post pivotally mounted thereon, a thread carrying member on the post, thread slots in the member and post in registering relation, said parts constructed and arranged to move out of registering relation'when engaged by a knot or the like in the thread.

8. A. thread clearer comprising a base, an

arm with a post pivotally mounted thereon, a swinging member on the post, thread carrying slots in the post and swinging member normally in alignment, said members constructed and arranged to move relatively out of alignment when engaged by an enlarged section of the thread.

9. A thread clearer comprising a base, an arm with a post pivoted thereon and normall in predetermined angular relation to the path of the thread, swinging memher on the post, the said member and post slotted in the plane of the path of the thread, said members constructed and arranged to change relatively the planes of their slots and the angular relation of the arm to the path of the thread to be changed by an enlarged section of the thread, and a member adjacent the thread slots to guide the thread thereto.

10. A thread clearer comprising a base, two relatively movable members movably mounted thereon, one of the members carrying the second member, a thread slotin d members through which the thread asscs. the members constructed and arrangeiil to swing relatively and to break the path of the thread when an enlarged section of the thread engages the members.

ll. A thread clearer comprising a base, one or more arms pivotally mounted thereon. a post on each arm, slots in the posts for the thread, a slotted movable member on each post, the slots in the posts and movable member registering normally when in operative relation, the posts constructed and arranged to swing and break the registration of the slots when engaged by an en.- larged section of thread In testimony whereof, I have signed my name to this specification.
